116/121
What is the probability of choosing a female or right handed student?
To solve this problem, you need to divide 116 by 121 using long division or a calculator.
If you use long division, you would write 116 as the dividend and 121 as the divisor.
Here are the steps for long division:
1. Determine how many times the divisor 121 goes into the first digit of the dividend 116. It goes 0 times, so you write a 0 above the first digit.
0
121)
116
2. Bring down the next digit of the dividend, making the new value 116.
0

116
3. Determine how many times the divisor 121 goes into the new value of 116. It goes 0 times, so you write a 0 above the second digit.
00
121)
116
4. Bring down the next digit of the dividend, making the new value 1160.
00

1160
5. Determine how many times the divisor 121 goes into the new value of 1160. It goes 9 times, so you write a 9 above the third digit.
